Clinton spoke by telephone with members of the "contact group" on Libya, which includes key European and Arab allies, and voiced strong support for Libya's rebel Transitional National Council as it plots a course for a democratic transition in Libya, State Department spokeswoman Victoria Nuland said.
"The plan is for the political directors to meet on Thursday," Nuland said, adding that the İstanbul meeting would allow the international alliance to discuss what types of help they may be able to offer the rebels.
"This must be and will be a Libyan-led transition," she said.
